There are few more perilous jobs in the world than that of "official
taster." But in Britannia, with a bit of skill in Taste ID, you can
both protect yourself from "accidental" poisoning and keep track of
your potions and potion kegs.

Using Taste ID

To use Taste ID to determine the contents of a potion or potion keg, or to test your food for inadvertent poisoning:

Click the blue gem next to the Taste ID skill on your skill list.

Target the potion or food you wish to taste.

If successful, you are told what type of potion you tasted, or, if you tasted food, whether it is poisoned.
